Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool to avoid burns.
Disconnect the battery to prevent electrical shorts.

2. Coolant Level Check

Remove the coolant reservoir cap.
If the coolant is low, fill it with the manufacturer's recommended coolant type.

3. Fixing Leaks

If leaks are found, replace any damaged hoses or connections.
Check the water pump for leaks and replace it if necessary.

4. Radiator Inspection

Remove the front grille or any obstructions to access the radiator.
Clean any debris or obstructions from the radiator fins with compressed air or a soft brush.

5. Cooling Fan Replacement

Test the cooling fan's operation; if it does not activate, replace the fan motor.
Disconnect the electrical connector and remove any screws or clips holding the fan in place.

6. Thermostat Replacement

Drain the cooling system to prevent spills.
Remove the thermostat housing by unscrewing the bolts.
Replace the thermostat and reassemble the housing, ensuring proper torque specifications are followed.
